Encouraging the use of biofuels to reduce carbon emissions is a'waste of time and money', a Canterbury researcher says. Under the Government's climate change policy, biofuels must make up 3.4 per cent of fuel companies' sales by 2012.
The director of the Advanced Energy and Material Systems Lab at Canterbury University, Susan Krumdieck, said setting targets for biofuels was a waste of time.
Because selling alcohol (ethanol) is marginally better than tipping whey down the drain and, due to import substitution, saving overseas money doesnt make it a bad idea. What is wrong is that the public doesnt know what the energy component is. Ethanol is less energy dense than petroleum gasoline. At 10 percent blend, the variance is at the margins but as the shortcomings are negative to the consumer, this should be explored and noted.
What Susan is alluding too and should be required for informed consumer acceptance is the well to wheel analysis. And that doesnt appear to be have been done.
